I think the problem many folks run into is thinking that techniques are exclusive to a particular style. Over the years, I've tried to internalize principle rather than technique so that I don't have to do a mental inventory of what throw/escape/counter goes where. If I can just remember that A. always goes against B., my options are greatly increased. My focus has been primarily Japanese grappling arts (Jujutsu, Aikido, Judo) but even during 3 years of Muay Thai study, I still tried to use principle to arrive at the right technique. Of course, it doesn't always work but even getting my head handed to me on a platter now and then can be educational.
